The electronic configuration of the specie underlined as in the molecule \(H _{2} S\) is ____________
A. \(1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{104} s^{2} 4 p^{4}\) B. \(1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{4}\) C. \(1 s ^{2} 2 s ^{2} 2 p ^{6} 3 s ^{2} 3 p ^{2}\) D. \(1 s ^{2} 2 s ^{2} 2 p ^{6} 3 s ^{2} 3 p ^{6}\)
Correct Answer: D
Explanation
In \(H _{2} S , S\) has gained 2 electrons to form \(S _{2}\) - . The electronic configuration of \(S\) - is \(S-1 s ^{2} 2 s ^{2} 2 p ^{6} 3 s ^{2} 3 p ^{4}\) \(S^{2}-1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6}\)
